AnswerPatrick,
Based on the model number of your unit it would appear that the correct part number for the door lock kit for your unit would be part number 137523400 which should have an instruction sheet included in it.

AnswerKelly,
The new door lock does indeed need a new door strike and it requires the wire harness, not just an adapter. The wire harness will run from the switch to the control board. Each wire on the harness will meet up to its desired location to install it. Meaning that the wire will go to the component that it is to be connected to.

AnswerDoug,
You will want to check the unit for error codes. The tech sheet will give you error code access information. This will give you an idea of what may be happening. Check your wiring as well to make sure that there are no loose or damaged wires. Make sure that there is not any corrosion on the connectors.
